Description
Technical field
The present invention relates to dipping compression consolidated floor and manufacture method thereof, specifically, is fast growing wood or bamboo wood dipping compression consolidated floor and manufacture method thereof.The consolidated floor of preparing with the method, intensity and dimensional stability etc. significantly improves, and processes, and have the performances such as wear-resisting, fire-retardant, mildew-resistant, anticorrosion, insect protected without extra enhancing, can directly use (especially can be directly used in outdoor) without covering with paint, lacquer, colour wash, etc.
Background technology
Along with the raising day by day of the flourish of national economy and resident living level, solid wooden floor board, with its comfortable foot feeling, the advantage such as warmth, elegant naturally, becomes the preferred material of people's ground decoration.Generally that footpath level is larger for the manufacture of the timber of solid wooden floor board; density is relatively high; texture is perfectly straight; the precious timber that natural defect is few; the in the situation that of our times forest reserves worsening shortages; in addition the protection of various countries to environment and the forest reserves, rises steadily wood raw material price, produces required assortment and cutting from being more and more difficult to meet existing solid wooden floor board.Many solid wooden floor boards manufacturing enterprise cannot produce smoothly because of starving or rise in price, ensure the sustainable and healthy development of solid wooden floor board enterprise, especially can be based on existing wood raw material supply situation, and can produce the solid wooden floor board that does not change its serviceability or there is higher serviceability, must innovate at raw material (as a large amount of use fast growing woods, bamboo wood replaces footpath level, the precious timber that density is larger) time, improve or innovate existing floor production technology, improve the comprehensive utilization ratio of wood materials, especially (footpath level is little how to make full use of the quick growing species of trees, density is low, material is soft and intensity is low), the production high strength such as bamboo wood, the floor of high-dimensional stability and high-weatherability, that solid wooden floor board industry must be faced and problem in the urgent need to address.
Solid wooden floor board is had relatively high expectations to the quality of log especially footpath level, along with timber by utilize wildwood be main be main transformation to utilizing quick-growing plantation, supply and footpath level as the precious log of ground board raw material constantly reduce, be that raw material production solid wooden floor board becomes inevitable choice gradually and adopt fast growing wood and bamboo wood, but the shortcoming of fast growing wood is as large in Variations of Wood Properties, material is soft, density is low, dry-shrinkage deformed large etc., its manufacture for solid wooden floor board is very limited, especially fast-growing small dimension wood (diameter generally only has several centimetres to tens centimetres) is processed into particularly difficulty of solid wooden floor board.Therefore fast growing wood must be carried out to the production that intensive treatment could be used for solid wooden floor board.
At present about the method for fast growing wood intensive treatment mainly contains two kinds: compressed carbonized and impregnation process.
Publication number is that the Chinese patent of CN101486212A discloses one and utilizes quick growth poplar wood to produce technological invention of " compressed charing poplar three-layer wood composite flooring " completely, top layer in the three-decker of its composite floor board is after high temperature carbonization is processed, compound with poplar sandwich layer, the board using poplar board bottom of unprocessed mistake, though the top layer of gained three-decker solid wooden floor board is through intensive treatment, but it is not remarkable that the combination property on whole floor improves, and the natural structure defect of fast growing wood is still inevitable, the Chinese patent of publication No. CN102407548A discloses the method on a kind of production of the method by compression compact and high-temperature heat treatment fast growing wood floor, the fast growing wood sheet material that its content is is 18-30% by moisture content is placed in health again after the hot press heat pressing compact of 110-120 DEG C, after finishing, health again sheet material is placed in to baking oven or the dry kiln heat treatment of 180-210 DEG C, making profile density gradient is that two surfaces are high, the sheet material that sandwich layer is low, although this kind of processing method can obtain good profile density and distribute, but later stage heat treatment meeting causes the larger decline of fast growing wood structural strength.It is a kind of by poplar vacuum pressed impregnation process, method dry, that produce Compossite solid-wood floor plate with color matching layer, super thin natural wood skin decorating layer and the hot pressing of wearing layer assembly again that publication No. is that the Chinese patent of CN102605928A discloses, the method still needs the wearing layer that price is more expensive to be strengthened, in fact with the complex intensifying floor production method of MDF base material without difference in essence.The shortcoming of above method maximum is to utilize small diameter grade fast growing wood to produce, and products obtained therefrom generally can not be used for outdoor in addition.
Therefore, how to overcome the deficiencies in the prior art, can make full use of existing fast-growing assortment (or bamboo wood), especially the huge small dimension wood of output, without extra enhancement measures, Processes and apparatus is simple, invests low, without carrying out mildew-resistant, anticorrosion, insect protected, flame treatment, indoor, the outdoor equal floor that can use of the high-performance of dimensionally stable is the problem that must solve.
